Actus pontificum cenomannis

The Actus pontificum Cenomannis is a series of short biographies of bishops of the city of Le Mans, starting with the first bishop Julian, one of the Seventy Disciples. The core text was written in the middle ninth century, probably by a cleric or clerics of the cathedral of Le Mans, though it had several subsequent continuations into the central Middle Ages. Much of the information this core contains, including several charters and diplomas, is partly or wholly fictitious.

The "Actus" were probably part of an ambitious campaign to extend the bishop's rights over neighbouring monasteries, particularly the abbey of Saint-Calais, though the attempt collapsed at the royal council of Verberie in 863. The text is important as evidence for late Carolingian episcopal ideology.
